ABSTRACT:
A vibration test fixture includes a reciprocating slip table carrying an article subjected to vibration and shock testing. The fixture includes low oil pressure hydrostatic linear bearings supporting the slip plate during single-axis linear travel on the bearings. The slip plate is mounted to each bearing by a single-axis guide system of confining the slip plate to reciprocating longitudinal travel on a general planar, two-dimensional bearing surface which supports the load of the slip plate during its travel. The guide system restrains relative movement of the slip plate laterally and vertically with respect to the bearing surface. A film of lubricating oil is supplied to the bearing surface to lubricate the sliding longitudinal travel of the slip plate on the bearings. The film of lubricating oil is also supplied to the lateral and vertical restraint areas of the bearing. The bearings produce controlled lubricated single-axis travel of the reciprocating slip plate while supporting the entire load of the slip plate and the article under test.
